    Hi there Andrei

    I would like to know if all the S551 models have the same look and feel when it comes to the physical structure. I intend purchasing the S551LA from an online shop and went to view the S551 (core i7, 8GB RAM, 1TB HDD; there was no indication if it was an LA or LB) at a walk-in store.

    Would really appreciate your help.
    Thank You

      all models are the same on the outside, the differences lie on the inside. the LB has a dedicated graphics chip, the LA does not.

    Hey bro , will you give me some information?
    I bought this laptop Asus K551LA core I3 4th generation. Can I upgrade the processor ? To core I7 ? And it had Intel HD graphics 4400 integrated. Can I install an additional Nvidia graphics card ?
    It’s best if you review this laptop bro.
    Hoping to get a response from you.

    I can safely say, if your screen makes cracking sounds, call in warranty.
    It will not last 2 years and the hinges will separate from the screen.

    SO, if like me, just 4 months out of warranty period, you have to pay half the original price to fix this poor design & quality issue.
    Google Vivobook S551 screen hinge and see for yourself.

    Hi! Ive got :Windows 10 Pro NL ( x64 – 64 bit )

    Full Activation

    CPU: Intel(R) Core(TM) i7-4500U CPU @ 1.80GHz

    Memory: 8076 MB DDR3 SDRAM 1596

    Disk: 500 GB

    Display adapter: Intel(R) HD Graphics Family(1.00 GB)

    Display adapter: NVIDIA GeForce 740M(2.00 GB)

    Motherboard: ASUSTEK COMPUTER INC. S551LB(Intel Haswell-ULT)

    Monitor:72.3 inch, 1366 x 768

    Monitor:15.4 inch, 1366 x 768

    Notebook

    My question is.. Is it possible to change the Intel or the Nvidia 740M Videocard for a better or/and faster one? Which one would you prefer if its possible?

    My second question: How do i know if my drivers are the correct ones and that they are up to date? Is there any program that is perfect for doing that and is always uptodate?

    And my 3rd question is: I got 8GB DDR3 RAM can i upgrade it to 12 or 16 maybe?

    My 4rd and final question is: Since i upgraded to Windows 10 my bluetooth wont work proper. Its detected in the Actioncenter but not @ device manager or PC options. in services.msc they are operating Could you help me out?

      1. No, GPU or CPU are not upgradeable on 99%of the available laptops.
      2. Use Windows update or go the the laptop’s manufacturer website and download rivers from there. for the Nvidia graphics you could also look for the latest drivers for your chip on Nvidia’s website. Google is your friend here.
      3. Would have to know the exact name and model of your laptop to answer that.
      4. It’s a drivers problem but there’s little I can do. Device Manager or HWInfo will tell you the name of your Wifi chip (which includes the BT module) so you can then look for the latest drivers for it. Again, Google is there to help.

        Thank you very much for the quick response. Waiting on ASUS service for several days already……….. Nothing!

        This is the information i could find on the stickers of my ASUS Notebook:

        ASUS S551L NOTEBOOK

        S551LB-CJ006H

        E3N0CX048602103 24M

        MDF 2014-03 CN9210

        CM5: CQ10 15100-0748L200

        Windows update is up-to-date it says.
        I already installed all the updates given by WU.
        Tried also: net stop wuauserv And net stop bits, deleted SoftwareDistribution and started both again after a reboot.

        Thought maybe WU was the problem. It seems after reading all logs there are no problems with WU or any other update. Videocard runs like charm and got latest update installed.
        To bad i cant replace the card for a better one. Seems 740M runs great but this card is just not good and fast enough for me :)

        Qualcomm Atheros AR9485WB-EG Wireless Network Adapter is given as my WiFi chip i guess?

        Still, No bluetooth detection anywhere except in the actioncenter and i dont know what is the correct driver to download and install then now.
        Found several different drivers when searching on google.
        Perhaps you know which one to install? Would mean the world to me!

        Keep up the good work Andrei, and thanks a lot again!

      This offers details on upgrading the RAM: https://www.youtube.com/watch?v=rJxaMFtcJaA , and there’s some extra in the article. From what I remember, this laptop comes with 4 GB of RAM on board and can take another 8 GB DImm for a total of 12 GB. Yours probably has a 4 GB DIMM , you’ll have to replace it. Software like HWInfo can show you more details on the type and amount of RAM.

    Once again, you are the man Andrei! I found the driver. Seems to work on other peoples devices so lets hope on mine to. If not, ASUS should prepare themselves on a massive riot tomorrow ;) Just kiddin’ then i just have to wait for the next driver or call asus customer service to pump some awesome beats out of my Bose system again. But Andrei for now you did a way better job than a HUGE company like Asus and i owe you big time! Keep up the good job and i shall reply later if this Bluetooth driver works under Windows 10 Pro in my case and when i updraded my RAM to 12.

    Well done mate!

    Bonjour, je m’appelle Rodrigue KENNE.J’ai un souci avec ma machine asus vivobook S551LB 1.0 . Elle ne detecte plus la batterie. Il y’a une croix rouge sur l’icône de la batterie et on affiche”aucune batterie détectée”. J’aimerais savoir s’il y’a moyen de remédier a ce problème. Merci.

    • Andrei Girbea

      The battery is probably dead, this happens after a while. You should address your issue to an authorized service and they could offer a more detailed reply.

    Hello Andrei Girbea,

    How can I enable Asus S551LB laptop keyboard and mouse. At this time keyboard and mouse are not working.

    Thanks,

    Thx for the complete and detailed review Andrei,
    especialy your article about upgrading the RAM.
    My version of S551LB , comes with only 4GB RAM,and no SSD, evertything else the same.

    Upgrading to WIn 10 with only 4GB RAM, proved disastrous. I kept getting " the instruction at 0x00000000xxxxxxx referenced memory at 0x0000000000xxxxxxx. The memory could not be read"
    and using the Asus VivoBook app ( shortcut using botton on top of numpad #7), I could see that it is using over 3GB of RAm of the toal 3.9 GB RAM available.

    Now, could you tell me how Can I speed up the CPU speed ? since you said it could go up tp 3GHz?

    • Andrei Girbea

      December 14, 2017 at 4:39 am

      The CPU adjusts its speed automatically based on the tasks it has to handle.

      Win 10 works fine on 4 GB of RAM without errors. I'd reckon something went wrong with the upgrade, you should try to perform a clean install from an USB drive, you'll find details about it online. Backup your data first though, a clean install requires a format of the drive from the Windows setup app, so you'\ll loose everything you already have on it and end up with a fresh computer, just like the one you take out of the box.
